1. Several cardiovascular and respiratory measurements have been performed in eels before and after intravenous injections of adrenaline. These experiments have allowed a comparison to be made of values for the cardiac output determined directly (Q) and using the Fick principle (QF) on individual fish under these two conditions. 2. Under control conditions it was shown that QF/Q = 0.72, indicating that about 30% of the mixed venous blood afferent to the gills is returned directly to the heart… CONTINUE READING
